How can one choose the right capacitor for the job?
The two most critical aspects to consider are performance and price. For many applications, such as woofer low pass shunt circuits and impedance equalization traps, one need not spend a fortune on capacitors and can usually get by with a single Zen cap. In most cases, bypassing with a Harmony or Crescendo cap will improve performance, but it is not always necessary. For tweeter applications, it is imperative that one use the best combination of capacitors one can afford, and we strongly recommend Cascade Bypassing whenever possible. See our Bypassing section for more information. It is not uncommon in high performance systems for the tweeter network to cost more than the tweeter. What is the difference between a metallized capacitor and a film-and-foil capacitor? The difference is in the conductor layers. A metallized capacitor has a layer of aluminum conductor vapor deposited on a dielectric film. This metallization layer is very thin – on the order of Angstroms. Two layers of the met
